I prefer Drops. I love to be floating, but also, I love launched coasters. I have only been on Rock'n'Roller Coaster, The Hulk and Revenge Of The Mummy. I just love the launch on the RnCR. It is just absolutely brilliant. But I love the 2nd drop on SheiKra, especially in the back row. It is amazing, you come flying out of your seat. Also, I remember Dragon Khan, I was 8 at the time and I wasnt the correct height to go on it, so I sort of "Sneaked On!". I think it was because I wasnt the right height that made the drop brilliant.
So, to cap it off, I like Drops better. But then Launches are brilliant too.
